Recommendation
Choose the patient category according to the QRS morphology, rather
than the patient's age. Use Adult if the duration of the QRS base is 50 to
70 ms: use Neonate/Pediatric if the duration is less than 50 ms.
Weak signal
The signal may be weak due to the patient's constitution, the electrode
placement or other factors. A 1 mV calibration bar at the left side of the
ECG channel enables you to estimate the quality of the signal.
Recommendation
•
Use the strongest signal on channel 1 and compare the QRS
amplitude with the 1 mV bar; the height should be at least half of
that size. If not, change the lead or try a different electrode
placement.
Paced Patients
Paced pulse rejection is available for patient categories.
Recommendations
•
Derive the cardiac rate from pulse.
•
Look for a lead on channel 1, where the pace pulse amplitude is
zero to avoid paced pulses being counted as beats.
•
Whenever acceptable use the Adult category.
